About the Smart Meter And Power Limit Function
Q: How to activate the output power limit function?
A: For the ET system, this function can be activated by following these steps:
1. Make sure the Smart Meter connections and communications are functioning correctly.
2. Turn on the export power limit function and set the maximum output power to the grid on the
APP.
Note: Even if the output power limit is set to 0W, there might still be a deviation of a maximum of 100 W
when exporting to the grid.
Q: Why is there still power exporting to the grid after I have set the power limit to 0 W?
A: The export limit could theoretically be 0W but there will be a deviation of around 50‒100 W for
the ET system.
Q: Can I use other meter brands to take over from the Smart Meter in the ET system or to
change settings in Smart Meter?
A: No, because the communication protocol is integrated into the inverter and Smart Meter, other
meter brands cannot communicate. Also, any change to the manual settings could cause a
meter communication failure.
Q: What is the maximum current allowed to pass through the CT on the Smart Meter?
A: The maximum current for the CT is 120A.
Other Questions
Q: Is there a quick way to make the system work?
27
A: For the shortest resolution, please refer to "ET Quick Installation Instructions" and to the "PV
Master App Instructions".
Q: What kind of load can I use to connect to the backup side?
A: Please refer to User Manual on page 12.
Q: Will the warranty of the inverter still be valid if, for some special conditions, we cannot
follow 100% of the User Manual instructions for installation or operation?
A: Normally we still provide technical support for problems caused by not following the instruc-
tions in the User Manual. However we cannot guarantee any replacements or returns. So, if
there are any special conditions for which you cannot follow the instructions 100%, please
contact the after-sales department for suggestions.

Make sure the inverter is totally isolated from all DC and AC power for at least 5 mins before
maintenance.
• Heat sink: Please use a clean towel to clean the heat sink once a year.
• Torque: Please use a torque wrench to tighten the AC and DC wiring connections once a year.
• DC breaker: Check DC breaker regularly and activate the DC breaker 10 times in a row once per
